Hot Melt Adhesives

Hot melt adhesives are thermoplastic, 100% solid and contain no solvents or water. They are comprised of three main elements:

  • Polymers: provide strength and flexibility and give the primary mechanical properties
  • Resins: provide wetting and adhesion properties
  • Plasticizer: controls the viscosity and enables it to be easily applied


Hot melt adhesives can bond similar and dissimilar materials. They are applied to an initial material when in a liquid or molten state. After a short open time, the second material is brought into contact. At this point, the adhesives cool down and set quickly, bonding the two together.

In addition to their versatility, hot melt adhesives offer the following benefits:

  • Long shelf life
  • Elimination of the curing step
  • No loss of thickness when solidifying
  • Little to no VOCs
